Regarding the issue of "dkms make" not finding armv7l for the kernel headers, installing the following two shambolic links fixed it so I could build and insmod the driver:

lrwxrwxrwx 1 root root 3 Nov 29 00:38 ./linux-headers-4.19.94-ti-r42/arch/armv7l -> arm
lrwxrwxrwx 1 root root 3 Nov 29 00:36 ./linux-headers-4.19.94-ti-r42/armv7l -> arm

Thanks for the driver.

This was done on beaglebone black 4.19.94-ti-r42.
